Cutting, Sawing & P rofiling T echnology
Framag, Austria, has provided
QualitätsSägeZentrum GmbH (QSZ),
Germany, with an individual cutting
machinery concept in order to process a
variety of different material dimensions and
qualities. QSZ is a quality sawing company
for steel mills, forging companies, and pipe
mills.
Both of the company’s two factories operate
fully automated band and circular sawing
machines for cutting pipes, beam blanks
or solid material of steel, stainless steel
and non-ferrous metal. The company is
able to process material up to a diameter of
530mm.
The first phase of Framag’s work for QSZ
involved material positioning ‘for perfect
cut’ with a frequency-controlled infeed
and discharge conveyor. It also involved
two opposing laser units to control the
conveyors.
The result of the first phase was a
positioning accuracy of ±5mm. The sawing
lines with forwarding devices for raw
material are designed to be user-friendly
and allow easy operation of both units by
just one person.
In the second phase the sawing unit was
completed with a support grate, material feed unit (positioning accuracy of ±0.5mm)
and scrap removal device. This allows a
fully automated operation of the whole
sawing process.
The state-of-the-art circular sawing machine
– branded type KKS 1250 billets – is used
for sawing of solid material (round, square,
rectangular). It is equipped with a centric
main- and auxiliary clamping device and
height adjustable table.
The advantage is the hydraulic support of
bent or curved material and protection of
the saw blade against jam in the cut. This
allows much higher durability of the sawing
blades.
On average more than 50m² saw blade
tool life is achieved with this sawing
machine. These outstanding values
result from the technical combination of
a sawing column including a Hydropol®,
extreme torsion-stiff and robust sawing
gearbox. It also benefits from stable and
vibration-free clamping devices. The
combination of these three critical factors
reduces the vibration caused by the
sawing process.
The KKS 1250 sawing machine allows
cutting of round material with diameters
from 180-420mm and square bar steels
with edge length between 160mm and
400mm.
Sawing blade diameters from 1,100mm to
1,350mm are possible, while a user-friendly
Siemens PLC technics control system has
been implemented.
